Properties:
DEMFAL demulsifier bases provide excellent performance in resolving a variety of crude oil emulsions and are particularly effective when used in heavy crude formulations.
Several important performance targets are achieved when our intermediate bases are incorporated into a demulsifier package:
• Rapid water drop – Quickly reduce water-in-oil to levels of 0.1 to 0.5 percent
• Clear oil/water interface – Provide sharper interface between the two phases for easier separation
• Good dehydration of crude oil – Remove more water to get closer to commercial crude oil specifications
• High performance in heavy oil – Address problems arising from high viscosity
• High efficiency at low temperature – Reduce the expense needed to heat oil
• Cleaner produced water – Reduce oil-in-water levels for easier discharge or reinjection of water

1 The relative solubility number (RSN) was determined by titrating water in a solution containing 1 g of

is reported as the volume of water needed to make a solution turbid or cloudy.

Usage:
A demulsifier is a complex formulation of solvents and bases designed to meet a well’s specific needs. Since DEMFAL crude oil demulsifier bases perform specific functions in these formulations, we recommend the entire DEMFAL package kit be used in formulation testing.
